HP STORAGEWORKS ENTERPRISE FILE SERVICES WAN ACCELERATOR DEPLOYMENT GUIDE 87
7 - WCCP DEPLOYMENTS
To configure multicast
groups on the HP EFS
WAN Accelerator
• On the client-side HP EFS WAN Accelerator, at the system prompt, enter the
following set of commands:
client-SH > enable
client-SH # configure terminal
client-SH (config) # wccp enable
client-SH (config) # wccp mcast-ttl 10
client-SH (config) # wccp service-group 90 routers 224.0.0.3
client-SH (config) # write memory
client-SH (config) # exit
TCP Port
Redirection
By default, all TCP ports are redirected, but the HP EFS WAN Accelerator can be
configured to tell the router to redirect only certain TCP source or destination ports. A
maximum of seven ports can be specified per service groups.
NOTE: You do not need to configure source and destination ports on the router.
To configure TCP port
redirection
• On the client-side HP EFS WAN Accelerator, at the system prompt, enter the
following command:
client-SH (config) # wccp service-group 90 routers 10.1.0.1 flags
ports-destination ports 135,139,445,80
Specific Traffic
Redirection
If redirection is based on traffic characteristics other than ports, ACLs on the router can
define what traffic is redirected.
For example, if you only want the traffic destined for IP address 10.2.0.0/16 to be
redirected to the HP EFS WAN Accelerator, you would configure the router in the
following manner.
To configure specific
traffic redirection on
the router
• On the router, enter the following set of commands:
Router> enable
Router# configure terminal
Router(config)# ip wccp version 2
Router(config)# access-list 101 permit tcp any 10.2.0.0 255.255.0.0
Router(config)# ip wccp 90 redirect-list 101
Router(config)# interface fastEthernet 0/0
Router(config-if)# ip wccp 90 redirect in
Router(config-if)# end
Router#
TIP: Enter configuration commands, one per line. End each command with CTRL-Z.
Load Balancing You can load-balance using WCCP. Traffic is redirected based on a hashing scheme
and the weight of the HP EFS WAN Accelerators. You can hash on a combination of
the source IP address, destination IP address, source port, or destination port. The
default weight is based on the HP EFS WAN Accelerator model (for example, for the
Model 5000 the weight would be 5000). You can modify the default weight.
